TOYMODS FACEBOOK PAGE - For all of those out there who stalk people using Facebook, Toymods has an official Page. (well there has been one for a while, we just found it again.) LIKE Toymods Car Club to keep an eye on upcoming events.

We are starting to make some improvements to the forums, Part of this change is the Classifieds are being closed with the Toymods Facebook Group being setup with the classifieds section. Current ads can still be posted in to close out current sales, but no new posts can be made whilst we do some pruning.

Re: Hydraulic Clutch Bearing Setups W55 W57 W58 R154

Are these kits still available.
I have an MA-70 7M-GTE R154 with OS Giken twin plate and stock master cylinder.
Can anyone confirm if the stock master is OK or that failing if it can be bred out to the required diameter.
I recall reading somewhere else that there is also the possibility of too much travel and a pedal stop I required

Yes the kits are still available. They work with OS Giken.
As for the stock master they work with it but depends on how much throw you clutch needs to release.
What we have been doing here in NZ is boring out the stock master cylinders and fitting a 3/4" piston into them. Only costs around $100nzd to do so.

I got one of these Quater master hydro bearing kits with tilton twin plates for my 600hp ma71 2jz from Barry & I have never looked back since.
It eliminates all these push/pull conversion kits with a million moving parts.

There seems to be two master cylinders, the steel ma-70 one and the alloy jza-70 one. I have the former, if that can be modified to a larger bore thats great news. Mine has been rebuilt with a stainless sleeve and never used, be good to start with another used unit

Yep thats my motivation for looking into this too, what master cylinder setup are you using?

Re: Hydraulic Clutch Bearing Setups W55 W57 W58 R154

I just wanted to let you know that I have FINALLY fitted this to the car mate.
The little alloy plate with the stud that is there to stop the mount from rotating did not suit the bolt spacing in my gearbox so I had to drill a new hole for the bolt and drill and tap a new hole for the stud and now it is all in there happy days.
Very easy to measure and setup, will know soon how it works
